Hi, all
I wrote a simple program with inb() and outb(). However, it reports the segmentation error when running it.
The code follows as: --------------------------------- #include <asm/io.h>
#define LPT 0x378
void write_LPT(unsigned char byte) { outb(byte, LPT); }
int main() { write_LPT(LPT); printf("Value:%c", inb(LPT));
} ------------------------------------------------------
Thanks,
Belinda
